- DOOR-OPERATING MECHANISM.

Specification of lLetters Patent. Patented Oct. 26, 1909.

Application filed February 4, 1909. Serial No. 476,032.

Be it known that I, HAROLD ROWNTREE, a citizen of the United States,residing in the city of Chicago, county of Cook, and State of Illinois,have made a certain new and -useful Invention in Door- Operating Mech- 1anism, of which the following is a speci-fication.

. In many instances it is desirable to provide means within an entranceor doorway to divide the same into separate passages, the Aone capableof use as an entrance and the other as an exit, and in conjunctiontherewith to employ doors respectively controlling said exit andentrance. lThis is particularly desirable Ain case of doors employed oncars thereby aording separate entrance and exit ways for passengersentering and leaving a car and hence very greatly facilitating thehandling of the passengers in street or other railway traiic reducingthe ltime required to load and unload the passengers and materially`aiding in the 'collection of fares.

My invention relates to doors andltheir operating mechanism embodyingthese characteristics. y Y

The invention consists substantially in the construction, combination,location and relatlve arrangement of parts, all as will be more out inthe appended c aims.

Referring to the accompanying drawing, and to the various-views andreference signs appearing thereon,-'Figure 1 is a view in horizontalsection of the endof a car showingin plan an arrangement of doors andoperating meansI therefor embodying principles of my invention. Fig. 2is a View in side elevation, parts broken oil", showin a somewhatdiiierent arrangement embody invention. Fig. 3 isla view similar 'toFig. 1 showing in plan the arrangement of Fig. 2. Fig. 4 is aAviewsimilar rto Fi 2 showing another arrangement include Within the scope ofmy invention. v

In carrying out my invention I provide a standard, post, or otherobstructionwithin theentry way of a door opening and I arthrough suchdoorway, and I-.provide means for controlling the operation of the door,

ing my said means being ca ableof location atV or central from .anyesiredl or convenient point. In the operation ofthe doors I provideforthe opening of the vdoors on one side. ost, standard or otherobstruction,

of the in one direction, while the doors on the other side of such post,standard or obstruction are arranged to open in theother direction,

therebyv affording a most 'simple and eiiicient arrangement for separateentrance andl exit nassageways through the doorway.v 'l j In connectionwith the door arrangement above referred to I also employ a movable steptogether with means for securingV a coinvthe car conductorfrom which thedoors and steps may be vcontrolled and-the fares collected. Theseprinciplesmay beferfnbodied ina wide variety of different constructionsand arrangements. While, therefore, Ihave shown, and will nowdescribevarious coning the desired results,I do not desire to be limitedor restrictedin the broad scopeyof 4my invention, fas defined in theclaims, to

an specificstructure or arrangement.

n the construction shown in Fig. 1 A designates a post, standard orother obstruction, and wh1ch, for convenience of description I. shallhereinafter refer to as a post intending to include -by this term astandard.1

,structions and .arrangements for accomplishy or other form of.obstruction for the puro oses intended. This post is arranged withm thedoorway to separate the same into .passageways on eitherV side thereof.;In

these passageways are arran ed doors which, in this ease, comprise thefol ing panels B, C, on the one side, and the similar anels B', C',onvthe other side. The panels B', are res tively hinged at one side'edgethereof to t e7 roximate side edge'of the other panels 0,62, the latterbeing connected at their extreme outer side edges to rock shafts D, D',respectively. A gear E, E', .is rigidly mounted concentric with theshafts D, D,

respectively, and these gears, throughI inter'- mediate gears G, G',drive ears F,F, rig-A idly connected to 'fthepane s B, B, in the axialline of their hinges. By rocking shafts D, D, the panels C and Cy areswung Ainto-open or closed position, as required, while, coincidentlytherewith, the panels B, B, :foldy upon said panels C, C', orare'extended into line therewith. yIn practlce I preferto rotate the shaftsD, D", opposite '.'directions wherebyythe doormoyements in folding uponeach other and .in attaining, theirc'ompletely opened position willtravelin a direction corresponding tothe passenger movement. Thus thedoor section C will be swung outwardlyin the exit passage way whilesection C', will swing inwardly 1n the. entrance passageway, asindicated by the arrows. In connection with the post A, I

have shown a'railing H, arranged to extend inwardly into the c ar, wherethe apparatus 'is used on a car, thereby extendin the passageways insidethe car and de nin the `s ame,'c while' at the same time affording a lconvenient station for the car conductor within thecar, from ywhich-theoperation of' .the doors maybe controlled, as, for instance, by means ofa control handle J, and connections K, to suitable means, notshown, inthisiview but corresponding to the'operating shaft in Figs. 2 and 4.This railing I-I, also enables the conductor to collect the fares of thepassengers at a ,point within the car, thereby .insurin thecollectionofall the fares while, at tie same time the conductor is in a positiontoview theentrance and exit ways and vto control the same, in supervisingthe loading or unloading of assengers and to. himself be seen or observeby passengers or inspectors inside thel car. A

In Fig. 1,'I have shown the folding doorconstruction as applied to ltheside of aicar M,`where'there is no platform'-butitiis evi dent that thesame arrangement-may be employed oncars having end platforms, "in whichoase the doors maybe arranged to control the entry 'way from theplatform to the inside of the car' body, as indicated in kdotted lines.

In Fig; 2, the Shafts D,-D, nre-shew as being operated by gearconnection to an operating shaftvN, having a crank O, by which itrocked'tlirough the connections K, or otherwise, as may be convenient.The step P, isconnected to this operating shaft'N, so v as to rock orswing into .or out of position for use coincidently withv the-operationof the doors. In the forni shown in this figure of the drawinggh owever,thepost A', instead of being a fixed post asin Figl, is a shaft which 1salso rocked through gear connection with the'o 'erating rock shaft N.And

instead ofthe oorpanels C, C,having co-` operating panels hinged theretoas inthe arrangement shown in l, the rock shaft A', carries a panel B2,which extends on both sides of thel shaft A', thetwo-wings thereof l foruse as shown in Fig. 3. -In this case the railing if used, should be'.arranged in suitable larrangement with respect to `the lopenjposition'ofthe panel B2, to forni the extended passageway to and fromthe dooI-,

wa 15h the arran ement shown in Fig. 4,' I employ twosha ts A2, A3, toform the post or obstructionwithin the Y doorwayfa'nd dividing the sameinto 'passageways, and v`to each of these shafts I attach a door sectionor panel B3, B4, respectively, cooperating with the door sectionsorpanels() or saidshafts being suitably geared, yas shown to operatingshaft N, to oausey said panels B3, B4, to cooperate in direction ofmoveabove yexplaine A door construction, and controlling means therefor,embodying the principles of ment with the dpanels C, C', in opening, as

operation as above explained, is lspecially adapted forvuse onstreetcars, though `iti isv .to be understood that my invention is notto be limited or restricted v1n res ect to the luse to which it is 'tobe vut'. ere employed on street'cars I aVoi the necessity ofp'rovidingsliding pockets in the side lof the car toaccommodate the doors whenopened, and I am enabled to secure a-wid'e o ening of the entryway andalso to apply t e apparatus; i

to the'ends of cars where the sides thereof may be somewhat rounded orinclined with reference to the len h of the car.v
